With two selves, overlapping memories, Krystal awakens from coma.

Staring at herself, she can't help but feel sorry for herself, with memories the past Krystal withholds, she knew everything. The blurry yet confused emotions were clear.

They loved the same person, let it be the Yiyun or Amber.

"Pabo, I'm back."

Amber stood there hugging Krystal. 

A scene in itself deserves happiness.

What happens to the past Krystal, looking at her future self, sge knew she has to return to her timeline, return to the one waiting for, her Amber.

A long journey, but they found her halves again.
